To all wlomit may concern; r

Be it known that I, CHARLES C. MANKEB, a citizen of the United States, and a, resident of Des Moines, in the county of Polk and State of Iowa, have invented' new and useful Improvements. in Oil-Burners, of which the following is a specification.

My invention relates to ,improvementsin oil ne s, an it o i si he Combinetion struc ions an arrang m nts: heredescrbed, nd cl m di 7 An object of my invention is to, provide an oil burner which may be applied to varius uses, such as Cook oves, h a i g stoves, fu'nac he lik n by me o w i h su ta n al y P r e omb s i n i fie ed, the eby n m zing i e l..

A further Object of my invention is to provide an oil hurner which dispenses with the need of auxiliarypressure such as that supplied from compressed air., The means by which this is accomplished consists 'in an arrangement whereby the pressure of the gasified fuel is sufficient to `force the gas into the interior of the conbustion chamber'and at the same time to entrain a sufiicient quantity of ar so as to efiiect complete combustion.

A further ob'ect of my invention is to' provide a burner of the type described which consists of relatively few parts and which is, therefore not liableto get out of order.

Other objects and advantages will appear in the following specification and the novel features of the invention` will be particularly pointed out in the appended claims. My invention is illustrated in the accompanying drawings forming' part of this application, in which:

Figure 1 is ,a side view of the device, certain parts being shown in section;

Fig. 2 1S a plan view of the devce;

Fig. 3 is a perspective view, showing certain parts in'position' ready for assembling; and

Fig. 4: is an enlarged section through a portion of the burner.

In carrying out Iny nvention I provide a base 1, this being preferably a `Inetal cast- The base may be `provided with legs 2 'and contains two chambers 3 and 45 respectively, (see Fig. 3), a'partition 5 separating these chamberst but terminating short of the rear as shown in Fig. 1, so as to prothe `opposite end of the cone.

vide a communicating passage 6. The top 7 of the base portion is provided with an upstandng rim 8 preferably of rectangular shape, this rim and the top constituting a hasa grate 11 and at one end has an open- Referring now particularly to Fig; 4, I have shown therein in detail the meansfor eeding he fu o l-E p p 13 mun cates with the compartment 4 throughan opening 14 in the top 7 of the base portion `see Fig. This pipe is the outlet pipe.

An inlet pipe 15 (see Fig. 1) co'mmunicates with the compartment 3 through an Opening 16. A removable plate 17 is provided for closi'ng the ends of the chambers 3 and'4. The fuel enters the pipe 15, passes through the chamber 3, through a passage 6, thence through the chamber t and into the pipe 13.

.At 18-I have shown aneedle valve which is manipulated bya hand Wheel 19 which permits the liquid fuel' to flow'through* a pipe 20 into'the receptacle containing the wick 9. Normally, the needle valve -18 is closed. Above the'valve casing is a fioat chamber 21 having a float 22 which is provided with a valve 23 arranged'to control the pipe 24 leading to the main valve casing 25. The valvecasing 25 'is provided` with a valve 26, which,t in this instance,

is shown as a needle valve and which is manipulated bya handle 27.

Threaded on one 'end of 'the valve casjing 25 is a, conical shaped member 28 which provided with a series of openings 29 on the sides thereof;` The cone 28 is provided on the interior (with aseries of inwardly extending fianges 30, these flanges a having'inclined portions 31 which are circular in contour and WhlCh are progressivelyl larger from theneedle valve toward p On the outside of the cone is a revoluble cover 32 having openings 33 which may register with the openings 29 in certain positions'of the cover, but which 'may vary the effective area of the openings 29 when the cover is revolved. A lock nut 34 is provided for securing the revoluble cover in position. At the end of the cone is a sheet of wire netting' 35.

From the foregoing description of the various parts of the device the operation` thereof may be readily understood. As has been stated before, in order to start the device the liquid fuel is permitted to flow through the pipe 20 by turning the handle 19. The ashestos wick soaks up the fuel and may be lighted by thrusting a match through the barsof the grate 11 or by raisingthe upper portion 10 slightly. Normally, the chambers 3 and 4 as well as the float chamber 21 are filled with oil, the oil entering the fioat chamber 21 as far' as the fioat will permit it. hen the fioat rises the valve 23 is seated, thus'preventing the passage of oil into the valve casing 25 and also stopping the flow of oil into the chamber 3 through the inlet 15. r

After the fuel has been ignited the oi chambers 3 and 4- become heated to such an extent that the oil is vaporizcd. When this occurs the vapor will forcethe oil back out of the fioat chamber and will permit the fioat to descend. valve casing 25 and past the needle valve;

It will be forced past the flanges 30 which tend to keep the stream of gas converged and to prevent its diverging toward the sides of the cone. Air is entrained, being drawn in through the openings 33 and`29, and more air is drawn in as the gas passes through the cone. The mixture of air' and gas is passed through the netting and into the combustion chamber, where it is ignited and consumed, the flames passing out through the grate 11. When the -gas is turned off by means of the handle 27 and the` burner cools down the oil Will again enter the chambers 3 and ?i and pass up into the `fioat chamber 21, thus closing the valve 23 and preventingthe flow of the liqnid 'fuel past the needle valve when the device is again` ignited, untilthe oil has been sufliciently heated to vaporize.

It will be noted that the device operates under its own pressure. This is comparatively slight, it being only necessary to elevate the oil tank or to place upon the oil tank a slight pressure to resist the pressure of the gas when the oilhas been gasified or vaporized. The device is simple in construction and, being` automatic in operation, it requires verv littleattention, while the comhustion efi'ected by thearrangement of parts is such that very little soot or carbon :is deposited in the combustion chamber. On the other hand the device develops high heat and `is especially desirable "for those furnaces which requirehigh temperature for their proper operation.

The gas will pass then into the ,the top th ereof.

Having thus described my invention, I claim:
